single-coil filament

Based on netting theory, linear equations for the single spiral, spiral and hoop filament wound toroidal pressure vessel were obtained.

基于网络理论，得到了纤维单螺旋、螺旋加环向均衡型缠绕圆环压力容器的线型方程。

Used for testing breaking tenacity, elongation at break of single yarn made of cotton, wool, jute, core-spun yarn etc, at the time including synthetic fiber filament, textured yarns.

用于测定棉、毛、麻、包芯纱的单根纱线及合成纤维长丝，变形丝的断裂强力和断裂伸长率。

The results of heat shrinkage rate of multi-filaments only express the maximum heat shrinkage rate of unbroken filament. The tensile curve of multi-filaments after heat shrinkage had some relationship with the distribution of heat shrinkage rate of single fiber.

结果表明，复丝热收缩率的测试数据只大体反映未被拉断的单纤维中的热收缩率最大值，复丝热收缩后的拉伸曲线与单纤维热收缩率分布有一定程度的相关性。

The p-type single crystalline Si wafers were used as substrates and CH4 and H_2 as gas resource, the pressure in the reaction chamber was kept at about 7 Torr and the filament temperature at 2200 ℃, the distance between substrate and filament was 7 mm.

生长纳米金刚石膜所用的硅衬底为p型单晶硅，气源为CH4和H2，石英管生长室内的气压控制在7Torr左右，钨丝的温度为2200℃左右，衬底与钨丝间距为7mm。

According to the maximum stress strength criterion, the burst pressure formula for the single spiral and the spiral with hoop filament-wound toroidal pressure vessel were obtained.

利用最大应力强度准则，得到了单一螺旋缠绕及螺旋加环向缠绕圆环压力容器爆破压强的计算式。
